Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment manufacturing, and specifically relates to a device for processing the arc of a metal narrow band with a small diameter. Background Art

[0002] At present, a small-diameter anti-loosening wheel is composed of a wheel body and an arc-shaped protective belt. The arc-shaped protective belt extends outward after bypassing half of the circumference of the wheel body. The two sides of the arc-shaped protective belt are fixedly welded to the two ends of the wheel body, so as to form a protective cavity for a rope or a pull rope between the arc-shaped protective belt and the wheel body. When processing the arc-shaped protective belt, since there is no special processing equipment to precisely process the arc of the protective belt, the operator can only clamp one end of the protective belt with a fixture, and then gradually bend the protective belt into a semi-circular arc bit by bit by holding it with pliers based on experience. Then, the wheel body is inserted into the semi-circular arc-shaped protective belt, and the two sides of the protective belt are fixedly welded to the two semi-circular ends of the wheel body with a welding torch. The substantial deficiencies of this processing method are as follows: the labor intensity of the operator is high, and due to the poor precision of the arc-shaped protective belt bent manually, after being sleeved on the wheel body, it cannot be completely attached to the wheel body, resulting in a complex subsequent welding process. Summary of the Invention

[0003] In order to solve the above-mentioned substantial deficiencies of the prior art, the utility model provides a metal narrow band arc rolling device with a compact structure, convenient operation, high arc processing precision, fast welding, and high processing quality.

[0013] The present utility model will be described below in conjunction with the drawings and embodiments.

[0014] As shown in the drawings, a metal narrow strip curling device is characterized in that it is provided with a shaping shaft 1, a backing plate 2, a base 3, a shaping plate 4, a clamping device, and an arc shaping plate 7. One side of the center of the upper end of the base 3 is provided with a positioning plate 8. The lower end of the positioning plate 8 is vertically and fixedly connected to the base, and one side is parallel or fixedly connected to the end face of the shaping shaft, so as to facilitate the lateral limitation of the narrow strip. The left end of the base 3 extends leftward and upward in a semi-circular shape starting from a point lower than the upper end face to form an arc shaping plate 7. The lower end of the base is fixedly connected to the clamping device. The shaping shaft is horizontally lying on the base. The axis of the shaping shaft 1 and the axis of the arc shaping plate are on the same axis line, so as to form a curling and shaping curve for the narrow strip between the shaping shaft 1, the arc shaping plate 7 and the left end of the base. One side of the arc shaping plate 7 is fixedly connected to the backing plate 2. The backing plate 2 extends upward to form a abutting surface for the narrow strip, and at the same time, it also facilitates the rapid introduction of the narrow strip.

[0015] The present utility model can be provided with a shaping plate 4 at the upper end of the shaping shaft 1. One end of the shaping plate is fixedly connected to the shaping shaft, and the other end extends horizontally outward to form a shaping surface, so as to facilitate the precise curling and positioning of the narrow strip during the curling process.

[0016] The clamping device of the present utility model comprises a plug-in frame 5 with an opening on one side and a fastening bolt 6. The fastening bolt 6 is in threaded connection with a threaded hole provided on the lower panel of the plug-in frame 5.

[0017] The utility model may also be provided with a supporting rib plate 9, the lower end of the supporting rib plate 9 is fixedly connected with the base 3, and the upper end is fixedly connected with the shaping plate 4, so as to facilitate the support of the shaping plate.

[0018] The left end of the supporting rib plate of the utility model is fixedly connected with the shaping shaft, so as to facilitate the positioning of the shaping shaft while supporting the supporting rib plate.

[0019] When the utility model is used for curling and shaping the narrow band, the utility model is first fixed on the chopping board through the clamping device, and one end of the narrow band is inserted into the curling arc shaping curve between the backing plate and the shaping shaft. During the insertion process, due to the guiding of the backing plate 2, it quickly enters the curling arc shaping curve. During the process of the narrow band entering the curling arc shaping curve, the narrow band is constrained and shaped by the shaping shaft 1 and the arc-shaped shaping plate 7. When one side of the narrow band leans against the positioning plate and abuts against the side surface of the positioning plate 8, the operator can press the other end of the narrow band against the upper side surface of the shaping shaft 1 to the upper end surface of the shaping plate, so that the inner arc surface formed by curling the narrow band is the same as the arc of the outer end surface of the shaping shaft 1. After curling is completed, the operator can move the narrow band out from one side of the shaping shaft 1 and sleeve it on the wheel body for welding. Since the diameter of the shaping shaft 1 is the same as the diameters at both ends of the wheel body, after the narrow band is curled by the utility model, not only the processing arc accuracy is high, but also the welding is fast and the processing quality is high.

[0020] Due to the adoption of the above structure, the utility model has the advantages of compact structure, convenient operation, high processing arc accuracy, fast welding, high processing quality, etc.
